SAS(R) 9.1.3 Companion for z/OS

Glossary 611
logical name
a name that is associated with an operating system data set name. Under z/OS, a
logical name can be a DDname, a fileref, or a libref. An example is the logical name
SASUSER, which is used in the SAS CLIST and in the SAS cataloged procedure. See
also assignment, DDname.
member
(1) a SAS file in a SAS library. (2) under z/OS, a single component of a partitioned
data set.
member name
a name that is assigned to a SAS file in a SAS library. Under z/OS, this term can
also refer to the name of a single component of a partitioned data set.
national character
any character that is specific to a language as it is written in a particular nation or
group of nations.
nibble
half a byte, or 4 bits (binary digits).
operating system data set
a collection of information that IBM mainframe operating systems such as z/OS and
OS/390 can identify and manage as a unit. IBM operating system data sets
correspond to files under other operating systems. Partitioned data sets (PDSs),
sequential data sets, and VSAM data sets are some types of data sets that are
supported in IBM mainframe environments. By contrast, SAS data sets are managed
by SAS software, not by any operating system, although they can be stored as
members of partitioned data sets or in sequential data sets on IBM mainframes. See
also PDS (partitioned data set), SAS data set, sequential data set, VSAM data set.
partitioned data set
See PDS (partitioned data set).
PCL (Printer Command Language)
a command language that was developed by Hewlett-Packard for controlling
Hewlett-Packard printers. Each PCL command consists of an escape key followed by
a series of code numbers. Different versions of PCL have been developed for use with
different models or types of Hewlett-Packard printers.
PDS (partitioned data set)
a type of operating system data set that consists of one or more separate units of
information called members, plus a directory. For each member, a unique name is
entered in the PDS directory. Partitioned data sets must reside on disk. See also
operating system data set.
portability
the ability of a program to execute in an operating environment other than the one
for which it was written.
portable
See portability.
PROFILE catalog
See SASUSER.PROFILE catalog.
random access
the ability to retrieve records in a file without reading all records sequentially.
record
a logical unit of related data that can be fixed, variable, or undefined in length.
